AutoSend

AutoSend provides a REST‑based email API designed for developers and marketers who need to send transactional, OTP, and marketing messages at scale. The service offers a clean, reliable endpoint that can be called from any language, with SDKs for Node.js, Next.js and other runtimes, as well as standard SMTP support for existing applications without code changes. Real‑time webhooks deliver delivery, open, bounce and failure events, enabling automated handling of email lifecycle data.

The platform includes tools for building and managing email templates, creating segmented campaigns, and monitoring delivery statistics through a web dashboard. Features such as domain warm‑up, dynamic audience segmentation, and unsubscribe group management help maintain high deliverability and compliance with email regulations.

AutoSend is positioned as a lightweight alternative to larger providers, pricing by volume rather than contact count, and is used by both large and small companies for a variety of communication needs ranging from one‑time alerts to ongoing marketing newsletters.
